Heart Failure
Supplements studied for heart failure.
Overview
Heart failure has one of the larger supplement datasets here (12 supplements, 48 studies). Iron, Fish Oil, Taurine, and Vitamin D each carry medium effect-size and medium evidence ratings (WA 72). IV iron may improve symptoms and exercise capacity in patients with low iron; oral iron appears less consistent. Fish oil may improve pumping function and reduce hospitalizations in existing heart failure. Taurine at 2–6 g daily may improve function and symptoms over weeks. Vitamin D may relate to prevention in some groups but does not appear to help established heart failure.
L-Citrulline (WA 44; low effect size, low evidence, medium trust) has limited low-rated evidence suggesting possible hemodynamic improvements in small trials. See the heatmap and evidence reviews below for full comparisons.
